FIRE ALARM SYSTEM

An Automatic fire alarm system is designed to perceive the unwanted presence of fire by monitoring environmental changes related with combustion. The fire alarm systems work on 230V supply and have provision for battery backup. The equipment provides dispatch output for interfacing with security panel, auto-dialer, audio alarm via siren or buzzer and have zone-wise visual indications for open, short, test or bypass conditions. Automatic fire alarm systems are proposed to notify the building occupants to evacuate in the event of a fire or other emergency and to prepare the structure and associated systems to control the spread of fire and smoke.

 

FIRE ALARM CONTROL PANEL (FACP)

It is the controlling component of a Fire Alarm System. The panel obtain information from environmental sensors designed to detect changes related with fire, monitors their operational reliability and provides for automatic control of equipment, and transmission of information necessary to prepare the facility for fire based on a predetermined sequence. The panel may also supply electrical energy to operate any associated sensor, control, transmitter, or relay. There are four basic types of panels: coded panels, conventional panels, addressable panels, and multiplex systems

 

FIRE DETECTOR

Detection of fire at initial stage plays very important role as it enables in suppressing the fire by means of the fire fighting equipments and prevent it from developing in to a major fire.

 

MAIN FEATURES:

  •  This system will provide alarm signal at the initial stage of fire.
  •  Detectors are located at strategic positions in the area covered by this system.
  •  Detectors are arranged in zones so that the area of fire can be easily identified.
  •  If any of the detectors in a zone is actuated an audio cum visual signal will be given
    to the control panel.

Most smoke detectors work either by:

  •  Optical exposure (photoelectric)
  •  Physical process (ionization)

FIRE HYDRANT SYSTEM

A fire hydrant is an active fire protection measure, and a source of water provided in most urban, suburban and rural areas with municipal water service to enable firefighters to tap into the municipal water supply to support in extinguishing a fire.

Various sprinkler system network designing can be done to cater the specific needs of the customers varying from residential to commercial and industrial.

 

CO2 FLOODING SYSTEM

Co2 at atmospheric pressure is a colorless, odorless and electrically Non Conductive inert gas, It has high expansion ratio which facilities rapid discharge and allows three dimensional quick penetration in the entire hazard area. Made from premium quality components, this system's importance lies in the fact that it has high efficiency to extinguish fire by reducing the oxygen content of the protected area below the point where it can support combustion. Designed to withstand every climatic conditions, these devices are widely used in following area of applications:


Description/Specification of Co2 Flooding System


We are engaged in offering a comprehensive range of qualitative Co2 flooding systems. These have high expansion ratio that leads to rapid discharge and facilitates three dimensional penetration of the entire hazard area in a fastest manner. Some of the advantages of Co2 system are :-

  • Fast in action

  • Non damaging nature towards the equipment

  • Non conducting

PUBLIC ADDRESS SYSTEM :-

It is an Electronic amplification system that is used as a communication system in public areas. Designed with amplifier and loudspeakers, this amplification setup is used to reinforce a given sound. Its main work is to guide commuters in case of any emergency.

 

FIRE HOSE CABINET :-

An arrangement of piping, valves, hose connections, and related equipment installed in a building or structure, with the hose connections located in such a manner that water can be discharged in streams or spray patterns through attached hose and nozzles, for the purpose of extinguishing a fire,thereby protecting a building or structure and its contents in addition to protecting the occupants.

This is accomplished by means of connections to water supply systems or by means of pumps, tanks, and other equipment necessary to provide an adequate supply of water to the hose connections. These are mainly red color cabinets have been placed at strategic location.

 

HOSE REEL:-

Hose reel system is intended for the occupant to use during the early stages of fire and comprises hose reel pumps, fire water tank, hose reels, pipe work and valves. The hose reel system generally serves as an initial fire fighting aid. When the hose reel is brought into use the pressure in the pipe immediately downstream of the pump check valves will drops below the field adjusted pressure setting of the pressure switch thereby triggering the pump to comes into operation automatically to feed a steady supply of water to discharge through the hose.Fire fighting hose reel is the part which can be easily accessible. The fire hose reel outlets should beproperly housed in glass fronted cabinet secured under lock and key.

 

FIRE EXTINGUISHERS:-

We offer our clients a wide range of fire extinguishers that comprise following types: A B C" Stored pressure type: Our ABC fire extinguisher is useful for fires of A, B and C types. Fire breaking out in these types involves cotton, wood, grease, flammable liquids, electrical wiring, live machinery and others. Capacity: 1Kg, 2 Kg, 5 Kg, 10 Kg, & above with ISI Mark


Types of Fire :
Class A Fire: Fire fuelled by ordinary combustible materials like paper, wood and cardboard. Class B Fire: Fire fuelled by flammable / combustible liquids like gasoline, kerosene, grease and oil. Class C Fire: Electrical fires caused due to faulty wiring or failure of electrical equipments. Class D Fire: Fire fuelled by combustible metals like Magnesium, Potassium and Sodium etc. Class K Fire: Fires involving cooking oils, trans-fats, or fats in cooking appliances. It is important to know the exact cause of fire and material present there that will decide the type of fire extinguisher to be used. Using the wrong kind of fire extinguisher can actually make the fire spread faster. Since some fires may involve a combination of these classifications, we suggest that your fire extinguishers ideally should be of ABC rating meaning it can control fire of A, B and C classes.
